Magento 2 Terser

A Bash script that uses terser to minify your JavaScript files and can be run in the root directory of your Magento 2 installation.

The script will minify all JavaScript files in the pub/static/frontend directory of your Magento 2 installation, except for those that are already minified or the requirejs-bundle-config.js file. The minification tasks can be run in parallel for increased performance.

Installation

You can install the package using Composer. Run the following command in your terminal:

composer require ibertrand/magento2-terser

Alternatively, you can download the file minify-m2-scripts.sh directly and save it wherever you want.

The script requires the terser command to be available. If you don't have it installed, you can install it globally with npm:

npm install terser -g

If you don't have npm installed, you need to install it first.

Usage

To run the script, open a terminal in the root directory of your Magento 2 installation and run:

vendor/bin/minify-m2-scripts.sh

This is assuming you installed the package using Composer. If you downloaded the file directly, you need to run the script with the full path to the file.

By default, the script will minify all JavaScript files in the pub/static/frontend directory of your Magento 2 installation, except for those that are already minified or the requirejs-bundle-config.js file.

The original files will be replaced with the minified versions. If your M2 instance is in developer mode, this might alter files outside of the pub/static/frontend directory because of symlinks.

You can run the script with the -v or --verbose flag to display the name of each file that is being minified. Alternatively, you can run it with --no-progress-bar or with --silent, which includes --no-progress-bar.

Parallel execution

The script supports parallel execution of minification tasks to speed up the process. To specify the number of jobs to run in parallel, you can use the -j option followed by the number of jobs or --jobs= followed by the number of jobs.

For example, to run 3 jobs in parallel, you could use either of the below commands:

vendor/bin/minify-m2-scripts.sh -j3
vendor/bin/minify-m2-scripts.sh -jobs=3
